BUTTERFLY COUNT

Join the Loudoun Wildlife Conservancy as it conducts its ninth annual butterfly count, centered in the Waterford area, at 9 a.m. Saturday. No experience is necessary; novices will be teamed with experienced leaders. Counters will also visit butterfly gardens in an area from White's Ferry in the east to the Appalachian Trail in the west, and from Point of Rocks south to Lincoln. This annual midsummer count, modeled after Christmas Bird Counts, is sponsored by the North American Butterfly Association.
